Hello everyone.
I want to thank you for your comments, they’re very encouraging.
I also want to apologize. This morning (Spanish time), I activated 10 units on eBay, but they sold out before I posted the link here.
I’ll build a few more, and this time I’ll let you know here first.
Thanks a lot. 
My vote:
Cart: clear red
PCB mask: black
PCB silk screen: white
The silk screen (PCB texts) will see as light red through the clear red cart, while the black PCB mask combine with the red cart to make the two main colors of the VB.
Hi
Really it is not a project, just info about the original cartridge, the target was to know how it works. I am new in the virtual boy scene and I have not found any information about it.
About the datasheets, if we can attach the info to this post, will be interesting to people than want to know it :-).
Thanks again!!!
